Given a pyramid with width 2cm, length 4cm and height 6cm. Find the volume of this pyramid.
The picture below shows the pyramid the width of 2cm, length of 4cm and height of 6cm.
To calculate the volume, we will use the formula for the volume of a pyramid. W, l and h are the width, length and height of the pyramid respectively.
Since the values for w, l and h are given, we can substitute w with 2, l with 4 and h with 6. After substituting these values, we can calculate for V as shown below:
Now, the calculated number 16 only has a meaning if we include the unit for it. Since the given units are in cm, the unit for volume will be cm3. Hence:
Clearly, the answer is B.
